How so?
As long as I don't touch the data plan it shouldn't change right?

I just changed my Family Messaging plan
The ATT Rep told me for the same $30, I can also get unlimited calling to all mobiles...
No change in contracts, rate, minutes, data, etc.

by the next time iPhone is out, AT&T will change something again.
Remember how iPad got unlimited traffic just to have it slashed to 2gigs 2 months later?

I can pretty much guarantee that they will come up with some new plan where you would have to drop your unlimited data. Like switching to iPhone5, where an account with iPhone5 would be incompatible with unlimited data. Obviously an artificial restriction, but it will make them tons of money.

I do hope you're wrong

I'll complain soooooo damn much if something like that happens... I have my business account linked to them as well as my grandparents U Verse...
and nothing is on contract except my personal line with my iPhone 4.

And "stable" is a relative term. You know what you are getting into when you jailbreak, and once you get a shitload of mobile substrate add-ons,
you are pretty much guaranteed to have problems.

This is why i decided to not jailbreak anymore. Had way too many problems and I didn't even have that many add ons. BiteSMS, SnowCover, and winterboard were enough to have my phone crash about 8 times a day

BiteSMS gave me problems at around 4.1 so I stopped using it.

Never had a problem with the unlock and installous (+ subsequent apps), which is (for me) 99% of the value of the JB.

Yeah those things will crash

I recently installed SwitcherPlus, which I really like... but I feel it's causing problems.

When both are on WiFi, FaceTime goes through and connects without an issue (though faster if she calls me rather than if I call her, she is stock 4.2.1, I am Jb 4.3.1)

If I am on 3G and I call her, it lags a lot and it didn't go through once out of the 3 times I tried.
If I am on 3G and she calls me, it goes through smoothly.

She is on Wifi at all times obviously.

So... it works for me

Stock ipsw file.

Did a full restore and it was fine. Jailbroke and was fine. Reinstalled almost all of the original programs and it was fine. I think one of the 3G FaceTime programs was crashing FT so I tried a different one (3G unrestricted instead of my3g) and now it's fine.

Has nothing to do with firmware, but rather with the traffic you generate.
Deep packet inspection would easily reveal that the traffic is originating from something other than an iPhone. Whatever firmware you use, all network traffic goes through AT&T routers, and they know what you are doing.

I understand what you are saying but how come this only started w/ 4.3.1? Did at&t just get fed up and said enough since they were coming out w/ their own plan?

it didn't "start" with 4.3.1. it takes time to develop software on that scale.
i am pretty sure they started working on it as soon as they realized that they can't milk jailbreakers and geeks (the main tethering market) for $20/mo, like they do with less technically inclined customers.
